Solder joint defects refer to situations where solder joints appear shrunken, incomplete, with voids, or where solder material is not fully present in through-holes or has not climbed onto component pads. Analysis of Causes and Corresponding Measures: These are the adverse phenomena and solutions in selective wave soldering. For further clarification, you can consult Silman…

There are two main methods for handling solder dross generated during soldering: chemical reduction to minimize solder dross generation and mechanical/physical extraction of solder dross. Wave soldering is a common process that generates solder dross, starting from the early days of hand-dipping solder pots. Common methods of handling solder dross include the use of solder…

Wave soldering is a technique used to solder components on a circuit board by inserting them into molten solder. In wave soldering equipment, the solder is heated to a sufficiently high temperature to form a wave-like “wave crest”. When the circuit board passes over the wave crest, the solder coats the soldering area between the…

In the PCBA processing process, there are two commonly used soldering methods: selective wave soldering and manual soldering. So what are the differences between these two methods, and what are their respective advantages and disadvantages? Let’s introduce the differences between selective wave soldering and manual soldering in PCBA processing. Firstly, from the perspective of soldering…

Selective wave soldering is an effective welding technique that achieves a perfect balance between welding quality and efficiency by controlling welding parameters and selecting welding areas. Below is a detailed introduction to the working principle, applications, advantages, and operational considerations of selective wave soldering. Selective wave soldering is an automated welding technology that utilizes the…

Welding processes have always been a focal point in the manufacturing industry, where high quality and efficiency are paramount. Selective wave soldering, as a new welding technology, is highly regarded for its flexibility and adaptability. By pre-programming welding parameters, precise control over the welding process can be achieved to meet the requirements of high quality…

Excessive length of component pins prevents individual desoldering when departing from the solder wave, or prolonged immersion of pins in the solder wave leads to burnt flux, reducing solder flowability and causing solder bridging between adjacent points. Large soldering angles decrease the probability of points departing the wave in a co-planar manner, thus reducing the…

Selective wave soldering, also known as selective soldering or robot soldering, is a specialized form of wave soldering technology developed to meet the growing demand for through-hole component soldering. Selective wave soldering machines are advanced through-hole soldering equipment. During soldering, they are similar to traditional wave soldering, using common solder bars or lead-free solder bars…
